4.15.1 High/Low Input Failure

These are continuous monitors. The voltage from the sensor is compared to failure thresholds defined in the software. If the voltage is less than the minimum threshold, then a timer starts to increment. Once this timer exceeds another threshold a failure flag is set and a DTC is stored. If the voltage exceeds the maximum threshold defined in the software, then a timer starts to increment. Once this timer exceeds another threshold a failure flag is set and a DTC is stored.
